    12 stage Phaser effect

    Coded something new during last weekend, another classic effect which sounds great with many instruments:

    12 stage mono phaser with internal (built in) LFO or an external modulation input

    Link to code:

    Internal LFO is active when there is no modulation input signal connected. The waveform is similar to parabolic (often described as hypertriangular in hardware effects). Instead of a usual rate/depth controls the depth is set by two params: top value and bottom value. Incoming modulation waveform, internal or external, is then scaled to operate within that range.

    Effect is not really cpu and ram heavy. T40 reported only 1% load.

    input [0] - audio in
    input [1] - modulation in (int16)
    output[0] - audio output

    One interesting use case of the phase shifter is a vibrato effect: set the feedback to 0.0, mix to full Wet (1.0) and adjust the top/bottom/rate values for the LFO to get different vibrato sounds.
